| ACEITE CRUDO DESGOMADO DIN 51605 Y REFINADO. Rapeseed oil as fuel DIN 51605:2010-10The standard for requirements “rapeseed fuel for Diesel engines” has just been published as an official DIN standard. The most
important changes to the former prestandard V DIN 51605:2006 are highlighted with yellow colour in the table below. The oxide ash
and carbon residue are no longer listed in the standard and therefore do not have to be analysed any more. 1. The visual appearance that has already been described in our reports has now become an official parameter of the standard.
2. The range for density was matched closer to values of rapeseed.
3. The unit for calorific value was changed from kJ/kg to MJ/kg.
4. A lower limit for the iodine number was cancelled.
5. The limit for flash point was lowered from 220 °C to 101 °C. This opens the possibility for adding permitted additives e.g. for the ignitability.
6. The limit for ignitability was increased from 39 to 40. The ignitability test is now done like “The constant volume procedure” according to DIN EN 15195.
7. The precision of determination of total contamination is insufficient. Therefore it was fixed in a footnote that this parameter is not applicable in case of a dispute. A CEN working group is trying to develop a more suitable procedure.
8. From 01.01.2012 there will be lower limits for the contents of phosphorous, calcium and magnesium.*REFINED RAPESEED OIL SPECIFICATIONFree fatty acid (as oleic) max……………. 2 %
